3e Amosse mom \8 ymmww Patented Mar. 24, 1931 UNITED STATES PATENT OFFICE AMOS SEYMOUR, F WESTERLY, RHODE ISLAND, ASSIGNOR T0 DBAIPER CORPORATION, OF HOIED-ALE, MASSACHUSETTS, A CORPORATION OF MAINE nannnss commc'rnn ron LOOMS Application filed September This invention relates to harness connecters for looms, In a loom each harness frame is usually operated by connecters secured at one N end to the harness-frame, extending around sheaves on the loom frame and then connected to a suitable actuating element, such, for example, as a cam-operated lever or the jack of a dobby. These connecters must be flexible, at least in the portion extending around the sheave, and they must be adjustable as to their length in order to secure the proper operation of the harness frame in the formation of the shed and to provide for such H changes as may be necessary due to changes in the weave, wear of the parts, or adjustment of the actuating mechanism.

The object of the present invention is to provide a simple and practical form of such 7 a harness-frame connecter in which the connecter is made in two or more parts and in which these parts may be longitudinally adjusted with respect to each other so as to adjust the length of the connecter and in.

which this adjustment may be made without longitudinal shift of the parts taking place during the adjustment.

In adjusting the length of such connecters it is usually very difficult to stretch them or- I. to draw the parts longitudinally together heyond the point required by the adjustment being made. The present invention enables this adjustment to be made in a simple and effective manner without experiencing this difliculty. In the drawings:

parts of the connecter when an adjustment is required.

As illustrating one use of the invention, a portion of a loom frame is shown having the arch 1 provided with the rotatable sheaves 2, a harness frame 3 beneath the arch, and a portion of a dobby mechanism 4 secured to the arch. A jack 5 forming a part of the dobby is illustrated, and this jack serves as an illustration broadly of a harness-frame actuator movable transversely of the loom to effect the raising and lowering of the harness frame, as required in the weaving operation. Usually two harness-frame c0nnecters are employed, as illustrated, extending from suitable attaching devices, such as the hooks 6, on the harness frame over the sheaves 2 to the jack or actuator 5.

In the preferred form of this invention, a portion of the conencter is formed as a flexible element 7, herein shown as a cord of suitable construction having at its ends eyes 8. One of these eyes 8 enables this flexible element to be connected to the harness frame, as by being hooked over the hooks 6. From the harness frame this flexible element extends up and around the proper sheave f2, and is provided with a terminal extension 9 herein shown as a strap, which may be of leather or other suitable material and which at one end is hooked into the eye 8. Another portion of the connecter is formed as a rod 10, preferablymade of wire and adapted for connection at one end to the harness-frame actuator. For this purpose it is shown as formed with a hook 11 to engage a wire loop 12 on the jack or actuator 5.

The end of the rod 10 opposite the hooked end 11 and the free end of the terminal extension 9 have apertures therethrough, and at least one of these elements has a plurality of such apertures thereof. In the construction illustrated, a single aperture is formed in the end of the rod 10 by bending it into an eye 13, while in the terminal extension 9 a plurality of apertures 14 are punched therethrough.

It will thus be seen that by shifting the apertures in the rod 19 terminal extenextending longitudinally sion 9 into different positions the length of the connecter may be varied.

A third feature of the invention resides in a latching element threadable through the aligned apertures of the rod 10 and terminal extension 9 without substantial longitudinal shifting of said rod and extension. and having means whereby it may be locked in threaded position. This latching element is preferably formed ofwire and comprises a shank 15 havlng at one end a hook-16 extending in a plane at right angles to theshank and s0 arranged that when the shank of the latch is parallel with the connecter this hook may I be caught around the rod 10 and thus engage the rod. Theshank 15 of the latch, at the other end, is provided with an arm-17 also extending at right angles to the-shank and adapted, as shown in Fig. 2, to extend through aligned apertures of the rod 10-and terminal extension 9. This 'arm ITterminates inan angul-arly-disposed threading and locking portion 18,

The operationof the device will be clear from the drawings. Assuming, for example,

engaged with the rod;l0,and the portion 18' moves into th position shown'in Fig. 2, and

thus the latch is locked and held in locking I position. It will be observed that as the latch is being threaded through the aligned apertures no substantial longitudinal shift of the parts of the connecter takes place, and thus the adjustment ofthe connecter may be made under. the most ditlicult conditions.

' Having thus described. the invention, what is clanned. as new, and desired to be secured by Letters Patent, is:

1. A harness connecter for a loom having a. harness actuator, a harness sheave anda her-- ness frame comprising a flexible element for connection to the harness frame and for extending therefrom around the sheave, a terminal extension of the flexible element, a rod for connection at one end to the harness actuator, the opposite end of the rod and the terminal extension having apertures therethrough, and at least one of the said elements having a plurality of apertures longitudinally thereof, and a latch having a shank with a hook at one endto engage the rod when the shank is parallel. therewith and at the other end an arm at right'angles tothe shank adapted to extend through aligned apertures ofthe rodlan r er n li x ens n terminat ng;
